Holiday 2012: Purchasing a New Lens

There are many variables that go into selecting the best lens for your needs. A good starting point is to establish what your current lens does not do. In other words, is my lens not wide enough, long enough or perhaps  fast enough?

What Are F/stops and How Do You Define a "Fast" Lens?

Aside from the lens barrel, a camera lens is composed of two main components, the clusters of individual glass elements and an iris, which is a circular set of blades that open and close to allow controlled amounts of light to enter the lens and travel through to the imaging sensor to create pictures.
